HUMIDIFYING DEVICE.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed February 42, 1914. Serial No. 816,047.

To all whom it may concern:

Be it known that I, ALBUR'ro BEMENT, a

citizen of the United States, residing at Y from a steam radiator, steam pipe, or other source of supply of steam.

One of the principal objects of the invention is to provide a device of this type which will operate in perfect silence.

Another object is to provide .an arrangement for maintaining the temperature of` the steam passing through the device above the point of condensation, thereby obviating the danger of blowing water into the room to the injury of carpets and furniture.

A. further object of the invention is to provide a humidifying device which will be compact and simple in itsconstruction, inconspicuous in appearance, cheap to manufacture, and readily attachalole to an ordinary steam radiator.

The invention has for further objects such other new and'improved devices, arrangements and constructions relating to humidifying devices as will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in the accompanying drawing, wherein- Figure 1 is a side elevation of a steam radiator with the humidifying device of my invention attached thereto; Fig. 2, a longitudinal sectional view through the device and a portion of one unit of the radiator;

Fig. 3, a sectional plan on line 3-3 of Fig.

2; Fig. 4 is a sectional plan on line 4 4 of Fig. 2.

Like characters of reference designate like parts in the several figures of the draweferring to the drawing, 10 designates a fitting preferably formed with a nipple 11 by means of which it maybe attached to the radiator, designated 12 in the drawing, or to some other element containing a supply of steam. Secured to the fitting 10 is an outer, preferably cylindrical, casing 13 and an inner, similarly formed, casing 14. rlhe tting is formed with a web 15 providing a steam port 16 opening into the chamber 17 within the inner casing 14. The web 15 has an interior threading for the threaded stem of a valve 18 which closes against a conical seat 19. The stem of the valve is .preferably packed by a packing 20 held in place by the bonnet 21. Steam is admitted to the chamber 17, when valve 18 is open, through a pipe 22 tapped into the web 15 and preferably extending through the nipple 11 into the middle of the radiator unit to which the device is attached so as to take the steam from the radiator at the place where it will be hottest and driest and at a point remote from the. opening in the nipple 11 so `that water of condensation outflowing through the nipple will not be drawn back into the device. The outer and inner casings v13 and 14 are' provided with heads 23, 24 respectively, having central openings into which is fitted a short tube 25'through which the vsteam from chamber 17 is discharged directly to the atmosphere without coming into contact with any part or element likely,

to cause condensation. rlihe head 23 closes the space 26 between the inner and outer casings providing a steam jacket which completely surrounds the chamber 17 through which the steam passes from the radiator to the atmosphere. -..Preferably the wall of the outer casing extends a short distance beyond the head 28 so as to provide a space 27, in which any water that may issue with the steam from the discharge pipe 25 will be Acollected and held until it is evaporated. A ring 28 stiiens the structure at the end and provides means for preventing water from dripping out if the device be disposed in horizontal position instead of in the 'vertical position shown in the drawings. 'i V Arranged within the chamber 17 is a body, preferably cylindrical in form, through which the steam 'is compelled to pass before it can reach the outlet pipe l25.

^This body, which is permeable to steam but The steam in passing through thesilencer is wire drawn and hence superheated so that it issues from the device to the atmosphere ofthe room in perfectly dry condition.

1n order to allow the escape of air from the steam jacket space l26 when steam is first turned on in the radiator, the device is preferably provided with av small pipe 32 which extends from the jacket space through the web 15 into steam port 16. inasmuch as, withvalve 18 open, steam from the jacket will pass' through pipe 32, as soon as the jacket is `iilled it will be possible to omit entirely the pipe 22 and depend upon steam from the jacket for the supply to chamber 17. I prefer to employ the p-ipe 22 as this insures drier steam. rl`he purpose of the steam jacket .contained in space 26is to prevent condensation of the steam in chamber 17 which, if it occurred to any considerable extent, would cause the device to sputter, diminish the volume of steam entering the room by wetting the silencing body and making it less permeable, besides possibly causing a blowing of water into the room. rThe body of steam in the jacket keeps all of the parts with which the steam discharging into the room comes into contact at .a relatively high temperature. Preferably the device is constructed as shown so that the jacket space is always open to the radiator whether valve 18 is opened or closed so that ifthe outflow of steam to the room is shut off for a time when the device is re-opened the steam comes into contact with surfaces which are hot.

While I have described my invention in a. preferred embodiment, modifications might readily be devised without departure from the principles of the'invention. Therefore 1 do not wish to be understood as limiting the invention to the particular constructions, arrangements and devices shown and described except so far as the same are made specifically limitations in certain of the claims herein. However, l do not make any generic claim herein to the construc' tions, arrangements of parts or combinations which are commonlto the particular form of device shown in thlsl application and to both of the forms of the invention shown in my co-pending application Serial No. 32,591, filed June 7, 1915; such claims being placed in said later filed case for the purpose of maintaining a proper line of division between the two applications.

Iv do not claim broadly herein the arrangement of the silencing element entirely ,within the device so that it and the discharge pipe therefrom will be kept hot bythe steam jacket. Nor do 1 claim broadly herein the provision of a steam inlet pipe separate from and terminating in a point remote tromthe passageway through which water g Liaaeae dof condensation runs back into the radiator.

taching it to a radiator or the like, and

formed with a steam port, of a hollow element secured to said Iitting into which said steam port discharges, a hollow. silencing body permeable to steam which is arranged in said hollow element and is open to the atmosphere at one end, an outer casing surrounding said hollow element so as to provide a steam jacket therefor which is in constant communication with the interior of the fitting, a valve to control the flow of steam through said steam port, and a pipe extending from said steam jacket to said steam port. j
